Things You'll Need
Cockroaches are estimated to be 300 million year old insects and are found in more than 3,500 species around the world. They can live in damp places in the house like bathrooms or kitchens and are hazardous to wallpaper, furniture, books and clothes. Cockroaches can easily spread germs and diseases. It is difficult to find their hiding places as they hide during the day and appear only at night. Large roaches are difficult to kill as they are more resistant to pest sprays and can quickly fly or crawl away. There are some actions you can take to keep your home safe and clear of infestations.

Clean the area. Add a tablespoon each of table salt and detergent in warm water and use this solution to wipe off all the floors and counter tops in the house.
Protect your home. Attach fine netting in all the doors and windows and fill any cracks or breaks in the floor or between the tiles to block the entry way for the cockroaches. Pour pesticides in the drains every night since they are the most common entries for cockroaches.
Kill the cockroaches. Combine together one part each of boric acid powder, white flour and white granular sugar. Use a little water and form small round tablets; place them behind the furniture, near drains or any other places around the house where cockroaches may access. The sugary scent will lure the cockroaches, and the boric acid will kill them.
De-clutter the house. Get rid of old newspapers and cardboard boxes. Thoroughly clean the mattresses and stuffed furniture using a vacuum cleaner and expose them to sunlight as often as possible. Large cockroaches usually enter the house through faulty plumbing and unprotected drains. Fix and insulate leaky plumbing in the house.
Protect from future infestations. Purchase a DIY extermination kit and follow the directions to spray all over the interior and exterior of the house. Alternatively, try Cedarcide non-toxic granules or another liquid concentrate – both easily available in the market for home use. Apply every two months to avoid re-infestation.
Buy a good quality insecticide spray. These sprays are handy to use to spray over a roaming cockroach.
Wipe all kitchen surfaces dry every night as cockroaches are attracted to moisture and dirty places.
Repeat the cockroach-killing steps as needed to kill all the cockroaches and stop re-infestation.
Boric powder may be hazardous if ingested so keep it away from small children and pets.
